A group of women around her own age.

There was a group of women swimming in the water, they seemed to be in the middle of a conversation. From Mackenzie's current distance, she was very nervous about her nudity. It was making her heart race. She gulped, and for reasons she started to swim closer. Mackenzie made sure to stay shoulder deep, it was her only hope of going unnoticed.

"So I spent a couple of days trying to get rid of these tan lines, but they're just so stubborn!" said one of the girls.

Mackenzie gulped. She realized, that thanks to a little privacy fence she had at home, she had no tan lines. There wasn't even the illusion of cover besides the sea water. Still she swam forward, thinking of something to say. To see if she could get away with conversation without her nudity being discovered. Worse case scenario, she might be able to say a wave knocked her swimsuit off.

But before Mackenzie could say anything, one of the girls noticed her.

Mackenzie made eye contact, and was completely unsure of what to do.

"Hey there!" One of the girls said in a friendly voice. "You new in town?"

Someone was talking to her now. While she was naked, and the didn't even though. This made a little warm tingle between the legs. Mackenzie had to be careful.

"N-no, I'm just here on vacation. This town has a beautiful beach!" Mackenzie managed to say.

"Can't argue with that," she said with a hint of pride. "You can hang out with us if you want, no need to swim all alone." She said, inviting.

Mackenzie gulped. None of these girls seemed to discover her nudity yet. She should back out while she had the chance, but her luck was holding out so well.
